Another thing also to keep in mind , Humans like structure , humans hate chaos and instability . My belief is that unless there is a full nuclear exchange , SHTF is not going to be like a ” Mad Max , Road Warrrior ” situation , especially in developed nations . Economic collapse seems to me to be the most likely event . On the street , that will be as ugly as Mad Max , but I dont believe it will last longer than a year or two at best , before there is once again a centralized authority , once again in control . That authority could take many forms . Depending on how the Federal government plays its cards , it could result in either regaining control , or start a civil war , resulting in the ultimate break up of the United States . For me , I think the US needs to break up , a few political analysts also see that as a possibility for the future as well . Just my 2 cents . , either way , good luck to all .
